Size of disk subsystem will be calculated on the basis of frame resolution and compression, rate of video signal frames per second, nuMBer number of cameras recording events to the hard drives and other recording parameters. 

...

Size of Disk subsystem (MB) = Time of storing an archive (days) x Cameras nuMBernumber x Rate of recording (fps) x3,51 x Time of guaranteed recording from a camera (h / day) x Average frame size (KB),

where Time of storing an archive is the required time of storing an archive from one camera, days;

Cameras nuMBernumber is the nuMBer number of cameras recording to the archive;

...

Time of guaranteed recording from a camera is the nuMBer number of hours of guaranteed recording from one camera to the archive per day,

...

The capacity of the system log database (high detection activity) = D * T * (0.48 GB / day);

where D is is the total nuMBer number of detectors created in system,

...

Size of metadata database = N×T×(5GB / day)– sufficient disk size plus a large reserve.

N equals equals the nuMBer number of video cameras in the system actively recording metadata;  T equals equals the period of time (nuMBer number of days) that metadata will be stored. By default, T = 30 days.
